Landeron 187 Chronograph problem

Question

Hello,

I am new to watch repair but have had some success thanks to all the smart people on this site.  I have recently cleaned a Landeron 187 chronograph that was not working and now is. However, when the driven wheel off the seconds wheel is engaged and the pivot tightened with the center wheel it slows /stops. With the driving wheel pivot off or with the pivot arm assembly loose,  the watch runs well.  Can someone help me with the adjustment necessary to correct this issue?

Thanks

Hi C

Pic please, makes working with you easier.

Regards joe

Thanks Joe.  I'm at work now and so I just posted a pic of the movement.  The problem is at the bottom of the image/movement where the center wheel ? or seconds wheel ? is engaged with the driven wheel / wheel arm assembly.  The driven wheel turns freely but when engaged and tightened, it stops the balance assembly.

On the most Landeron movements I worked with you could adjust the tension on that wheel by an oval shaped screw in the position showed on the Landeron 149 Movement I had lying around at home.
If you oiled and cleaned it well adjusting slightly on this screw would do the trick.

Hi C

I am not good with parts name, for reference to parts, if you will please go to OldSwissWatches.com to show the part, helpful.

It dose not sound serious, I agree with HSL, most likely just a matter of tension release.

By the way, anyone who likes watches is in love with landeron chrono.

Regards joe

Thanks HSL and Joe,

That did the trick!  It is a nice movement on what appears to be a vintage fake Navitimer. It all seems to be quality parts and construction.  However, with this movement, it only has two sub dials which is the giveaway!  I bought it long ago and it never worked.  As I had it in a box, I figured I had nothing to lose.  It does have a strange corrugated wire that runs between the watch case front and the bezel.  The next task is to try and figure out how to reattach the bezel.  I have never seen one like this before.

Just stumbled across this thread today but I had say, that is just a fantastic fake.  I think counterfeit watches are really interesting from the sociological perspective and that one strikes me as being really special; the amount of care and effort that went into creating it suggests genuine love of the real thing.

I think that beyond high-end counterfeit watches there are great skills, expertise and equipment, but the only love is for the money.

    • I've never used the Longines archive extract but it has to be applauded for offering this as a free service, I have however used the Omega extract service which has a charge attached to it, that service was also good and included the Model number and Name year of manufacture and which retailer originally sold the watch and in which country. I have also had good experiences with a company called Eberhard many years ago, I needed some parts for a old chronograph I  bought at a local auction  I needed a full set of hands a winding crown, and oval pushers, on the off chance they may still have these I wrote to them with the serial number and received a very nice letter back from them telling me that my watch had been manufactured in 1938 and was a two button 18ct rose gold chronograph and that they did have the parts and would be happy to supply them for 65 Swiss francs. Try doing that with any of the large manufactures, their response was a pleasant surprise. I had the watch for many years but sadly I had it stolen about 5 years ago.
    • Thank you for your introduction and welcome to this friendly forum. Where is NL
    • It's ok if that's how she self identified.
    • Personally I would see if incabloc springs fit.
    • Thanks a lot guys ... I'll do some test and show the results. I really love that dial though it's pretty stained and scratched so I'll try first with Rodico, Q-tips and distilled water and see how it goes. There is no financial risk as I got it for cheap ($40 shipped) but those 1002 dials don't often show up on the net and are sold for much more, even if they are damaged ... plus I have a nice 5500 case that's waiting for a dial    By the way ... did anyone of you ever drilled an ETA 2840 mainplate to make place for Rolex dial feets ? I'm asking because I have the case, the low beat ETA and a handset that could fit but I don't think I could ever cut the feets of a Beyeler Rolex dial
